What are the ACTUAL, BIOCHEMICAL reasons that alcohol makes a person vomit?

1 I don't know, this has never happened to me in my lifetime, maybe in a previous lifetime, who knows! ;-) .

2 Alcohol goes thru the stomach lining. It could be a shock to the stomach lining. It could be the sudden absorption shocks the blood into reacting.It could be that you are allergic to alcohol sometimes.

Allergies are not always constant. Do you really need to drink alcohol?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
